I've had low readings from this lot (low enough that the value of reading is lost as I get 0). A few other folks have seen the same issue.

Anyone else out there having issues with this Lot#? If this is the first lot# you are using this is a hard assessment to make as the packets do seem to read in high phosphate tanks, just low.

If you have been using the phosphorous tester for a bit and suddenly your values dropped, please chime in!
